Measurement System Overview
Sensors and transducers detect physical phenomena. Signal conditioning
components condition physical phenomena so that the measurement device
can receive the data. The computer receives the data through the
measurement device. Software controls the measurement system, telling
the measurement device when and from which channels to acquire or
generate data. Software also takes the raw data, analyzes it, and presents it
in a form you can understand, such as a graph, chart, or file for a report.
